Abstract: 443,080. Resilient mountings. ENGLISH, T. C., c /o Harland & Wolff, Ltd., Queen's Island, Belfast. July 13, 1935, No. 20067. [Class 108 (iii)] [See also Group XIV] A support for furniture or other loads comprises upper and lower frames between which sets of springs of different resiliency are interposed, the two frames being drawn together to such an extent that, before the load is applied to the upper frame, all the springs are subjected to a compressive stress equal or substantially equal to the load which will normally be applied. The more resilient springs may be metallic, e.g. helical springs, while the less resilient set may be non-metallic springs or elastic buffers or rubber &c. or pneumatic or hydraulic buffers. A bed or seat is for example provided with two frames 6 with helical springs 13 and non- metallic resilient blocks 14 of sponge rubber interposed between and recessed in sockets in the frames. The two frames are drawn together, by means of lacings of cords, wires, &c. passed through eyelets 15, so that both the springs and the resilient blocks are compressed to the same extent that they would be under the normal load. Preferably the springs and rubber blocks are so arranged that the latter are not compressed until a load nearly equal to the normal load is applied.

Title: Process for separating liquid hydrocarbons from waxes
IPC: C10G73/04
Filed: 1945-08-07
Abstract: In the separation of liquid hydrocarbons from waxes a sufficient quantity of an organo-silicon compound is added to the mixture to cause the wax dissolved in the oil to crystallise out on cooling so that the wax may be separated by filtration &c.  The oil may then be freed from the organo-silicon compound by distillation.  When the mixture of oil and wax is so rich in the latter that the mixture is solid at ordinary temperatures, it is melted before adding the organo-silicon compound.  The organo-silicon compounds used are selected from the class of organic silicanes and their hydrolysis products and polymers. They have the formula Ry Si Xz in which R is a saturated or unsaturated hydrocarbon radical, X is a halogen, another p  hydrocarbon radical or an -OR group, Y has a value 1, 2 or 3 and Z has a value of 1, 2 or 3; when Y + Z is less than 4, the remaining silicon valencies may be occupied by hydrogen.  The hydrolysis products and polymers of these silicanes may also be used and are preferred.  In an example a wax distillate from petroleum is cooled to freeze out the major portion of the wax, the oil drained off, 15 per cent. by weight of monoamyldiethoxy-silicane added, the mixture cooled further to freeze out the remaining wax, and the mixture filtered.  In a second example, 25 per cent. by weight of a monomethyl diethoxysilicane is added to the molten wax obtained from the above filtration and the solution cooled, causing the wax to crystallize out, leaving a small quantity of oil (containing silicane) as an upper layer which may be removed by decantation &c. In the dewaxing of lubricating oils the silicane may be allowed to remain in the oil, the pour point and viscosity index of the latter being thereby improved.  The process is applicable to animal and vegetable waxes as well as to hydrocarbon waxes.

Abstract: 1419992 Electro-erosion; coiling wire; shearing A G FUR INDUSTRIELLE ELEKTRONIK A GIE LOSONE BEI LOCARNO 27 April 1973 [27 April 1972] 20252/73 Headings B3V B3E B3H and B3W [Also in Divisions D1 and C7 An electro-erosion machine comprises a first driving means 3, 4 for forwardly feeding an elongate electrode 1 at a constant velocity and a second driving means 10, 11 for pulling the electrode 1 from the first driving means 3, 4 at a different velocity and for feeding it away therefrom. A spark erosion or electro-chemical wire electrode 1 of steel, tungsten, copper or brass is unwound from a reel 2 by a roller 3, driven at a constant velocity by a motor 5, and a roller 4 coated with rubber and pressed into engagement with the wire 1 by an adjustable spring 41. The wire 1 is pulled by a similar pair of rollers 10, 11 around guides 7, 8 which define the working length 9 of the electrode 1 and each of which comprises an abrasion resistant member (71) (Fig. 4a, not shown) and a member (72) of low abrasion resistance and good electrical conductivity. The roller 10 is driven at a constant torque or constant velocity greater than the velocity of the roller 3 thereby stretching the electrode 1 over the length 9. The wire 1 may be wound on a reel 12 or cut into disposable pieces by an electromagnetically operated knife 15. The wire 1 can be fed through a guide tube (171) (Fig. 9, not shown) before it is cut into pieces by a double edged knife (172) (Fig. 10, not shown) coupled to a ball joint (185) slidable in a channel (179) by a solenoid (177). The movement of the knife (172) is limited by damping members (184). In another embodiment (Fig. 7, not shown) the wire 1 is passed around part of the circumference of both rollers 10, 11 and is wound under constant tension on the reel 12. The wire 1 is alternatively coiled by a rotatable conical container (161) (Fig. 8, not shown) preceded by a guide tube (160). A pilot hole in the workpiece can be made by clamping the free end of the electrode 1 projecting from the rollers 3, 4, by means of a tube (210) (Fig. 12, not shown) compressable by a spring or fluid under pressure. After the hole has been formed, the end of the electrode 1 may be fed to the rollers 10, 11. A plurality of wire feeding mechanisms may be mounted on the electro-erosion machine, each mechanism being mounted in a cassette (80) (Fig. 6, not shown).

Abstract: 148,360. Daimler-Motoren-Ges. May 31, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Propelling.-Aircraft fitted with engines or groups of engines arranged outside the median plane have the engines controlled simultaneously in the same or opposite directions by different movements of the same lever. The connexions to the lever may be adjustable to enable individual engines to be controlled independently. Figs. 5 and 6 show a device for controlling the carburettors 5, 6, 7, 8 of four engines arranged in pairs on opposite sides of the fuselage and driving two propellers. The carburettor levers are connected by tension members 10, 21, 9, 22 to levers 26, 24, 25, 23 mounted respectively on the ends of a rod 31 and concentric tubes 32, 33, 34. The outer tube 34 can turn in a sleeve 14 pivoted about a transverse axis 15, and a handwheel 13 is rotatably mounted on the tube 34. Each of the concentric members 31, 32, 33, 34 is provided with a lever at its upper end which is normally locked to a toothed ring 35 on the wheel 13. Springs keep the members 9, 10, 21, 22 in tension. Rotary movement of the wheel 13 moves the levers of the carburettors 5, 6 in the opposite direction to those of the carburettors 7, 8, and rocking movement about the axis 15 adjusts all four carburettors in the same direction. Separate adjustment of the carburettors is effected by the levers at the upper ends of the members 31-34. A modification is described for controlling four carburettors without the independent adjustment, the four concentric members being replaced by a single member, and the levers 23, 24, 25, 26 by a double-armed lever. A modification is described for controlling two engines driving propellers on the two sides of the fuselage, and a third engine and propeller at the front of the fuselage. In this case, the carburettor of the third engine is connected to a sleeve on the control lever so that the lateral engines can be adjusted oppositely by a rotary movement of the lever without affecting the central engine, but all three engines are adjusted simultaneously in the same direction by rocking-movements of the lever.
